The LAC12 gene of Kluyveromyces lactis codes for an inducible lactose permease. We have determined the nucleotide sequence of a DNA fragment which includes the complete LAC12 gene. The 4.7-kilobase (kb) mRNA carrying LAC12 contained two open reading frames, ORFI (1761 bases) and ORFII (1266 bases), separated by a 573-base pair noncoding region. Mung bean and exonuclease VII mapping showed that ...

Fat in human milk is extremely variable and can represent up to 50 % of infant energy intake. To accurately determine milk composition and infant intake at 1 (n 17), 2 (n 17), 4 (n 17), 6 (n 15), 9 (n 6) and 12 (n 5) months of lactation, samples of fore- and hind-milk were collected from each breast at each feed over 24 h periods from an initial group of seventeen women. The content of fat in m...

binding protein,(CaBP) content and the empty liveweight calcium content. These measurements were carried out on rats eating a semi-synthetic diet since weaning containing 30 p. 100 lactose. In controls, carbohydrates were supplied in the form of starch and a vitamin D supplement was given. Administration of lactose caused cecum hyperplasia in ten 4-month old animals. The morphology, cell renewa...

Protein synthesis and eukaryotic initiation factor (eIF) activation are increased in muscle and liver of pigs parenterally infused with amino acids and insulin. To examine the effects of enteral protein and carbohydrate on protein synthesis, pigs (n = 42, 1.7 kg body wt) were fed isocaloric milk diets containing three levels of protein (5, 15, and 25 g x kg body wt(-1) x day(-1)) and two levels...

fifty six holstein lactating cows (71 days in milk; 35 kg/day milk production) were employed in a complete block randomized design of repeated measurements. cows were randomly allocated to two treatments based on their parity. cows in group 1 were fed a balanced total mixed ration (600 g concentrate /kg dm and 400 g forages /kg dm) with 50 g rumen protected methionine (rpm) per head per day (me...

The aim of the present study was to evaluate relationships between the presence of the two major bovine acute phase proteins haptoglobin (Hp) and serum amyloid A (SAA) and raw milk quality parameters in bulk tank milk samples. Hp and SAA have been suggested as specific markers of mastitis but recently also as markers for raw milk quality. Since mastitis has detrimental effects on milk quality, ...

the effect of different levels of osmolality and ph of lactose extender on the viability of bactrian camelspermatozoa was investigated. semen was collected from 10 bactrian camel bulls using modified bovineartificial vagina. in experiment i, the extenders consisted of 9, 10, 11, 12 and 13% lactose with respectiveosmolalities of 290, 333, 350, 376 and 419 mosm/kg and the ph of 6.9. in experiment...

The aim of this study was to evaluate biomarkers heat stress (HS) from an automatic milking system (AMS), the relationships between measurements temperature-humidity index (THI), reticulorumen pH and temperature, some systems parameters in dairy cows (rumination time (RT), milk traits, body weight (BW) consumption concentrate (CC)) during summer period. Lithuanian Black White (n=365) were selec...


 The purpose of this research was to determine the chemical characteristics fermented cow’s milk kefir in light green coconut shells (Cocos nucifera L. var. viridis Hassk). conducted from August Oc- tober 2020 at Laboratory Animal Products Technology, Faculty Science, Udayana University. experimental design used study a completely randomized (CRD) with three treatments and five replicatio...

Protein nanofibrils have recently shown unique properties preparing emulsions, with the stability improved after fibrillation of glycated proteins. The objective present study was to physical and chemical emulsions prepared different flexibility. Increasing ethanol level during heating aqueous whey protein isolate (WPI) solutions at pH 2.0 85 °C increased amount semiflexible highly flexible wor...
